TO ALL PERSONS TO WHOM THESE PRESENTS MAY` COME 'Be it known that I,Jnssn S. PERKINS, of Lake Village, of the county of Belknap, of theState of New Hampshire,--have invented a new and useful Machine forkMaking from Wire the Blanks or Shanks of the Needles ofKnitting-Machines; and I do hereby declare the same to be fullydescribed inthefollowing specification, and represented in theaccompanying drawings, of whichl A Figure 1 is a top view, Figure 2 alongitudinal section, and j Figure 3 a rear end elevation of suchmachine.

. The blank (or t shanl:,"as usually termed'by operatives,) which themachine makes,*hasv the form as represented in side'view in fi'fg 4.After having been so made from-wire by themachine, the blank has to beiattened, slitted, pointed, notched, bored, and bent by othermechanismbefore it becomes in a proper form to re'ceive the latch ortongue used for closing its h'ook 'usually made o'n the front end of theblank.

My machine forms each blank with a projection having the form as shownat `a in fig. 4, and, besidesthis, my' machine cuts the blank lfrom thepiece of wire from which it is to befmade, Ythe mahine producing from acoil of wire a. succession of such blanks, until such coil maybeentirely cutQup or converted into the blanks.

In the drawings, A 4denotesjthe frameof the machine, it having adriving-shaft, B, extended .across it at its rear part. This frame alsosupports, in suitable uprights or standards, a a', another shaft, C,which is revolved by means of a train of gears, D E F, arranged asrepresented. The gears D and E are fixed on the Vtwoshafts, and theth-ird gear is arranged between the other two, and supported by` ajournal, ZI, extended from an inclined bar, c, composing part of theframe. v j l v Atfthe rear Iend of the' frame A are two jaws, d e, whichare connected by a clampscrew,f, which goes through the upper and screwsinto `the lower of such jaws, such lower jaw being projectedfrom'theframe. i

The wire W, in its passage intothe machine, first goes between the twojaws d e, and bythem will be held l by friction suihcient to 4prevent itfrom being forced backward during the retraction of the carriage G ofthe machine. v

From the jaws the wireis extended' through'a die,f, projecting upward`from ancljbeyond the end of the movable carriage G, in manner asrepresented in igQQ. This carriage is to be supported within the frameA, so as to be capable of being moved horizontally .and longitudinallytheiein. A cam, H, fixed on the drivingshaftfserves, when revolved bysuch shaft, to advanceA the carriagawhich afterwards will be retractedby means ofa spring, I, connected to it, and supported on an arm, K,arranged as represented in tbedrawings. v v V In advance of the diefis'another die, g, which projects upward' from a lhorizontalA shaft, 7i,provided with a rctrac-tive spring, z', which is coiledaround Vtheshaft. One end of the spring is attached to the-shaft, andthe other'tothe frame. Furthermore,"an arm, k, 'extendeddown fromthe shaft 7i,brings up against an adjustable stop, l, screwed through' the front-endof the frame.

lNear the said frontend of the frame is another movable carriage, L,which rests against-the inner end of an adju`sting-screw, m, and carriesa die, n, .formed and arranged in manneras shown in'the drawings.A i Athird carriage,d\I, supported in groovesv madein the two standards, a a,so as to bec'apable of beingY moved vertically, supports a bending-die,o, 1and a cutter,p, and is forced downward by a,cam, g, and isretracted' by a spring, r, the said cam q being fixed on the' shaft C. ii 'The operation ofthe machine may be thus-explained:

The wire, after having been passed through the dief, and upon andbeyondthetop of the lowebender and cutter g, the carriage M will next descend,-so as to force the upper bender o down upon the wire, and between thetwo diesfg. In the mean-time the wire willbe cut oif by the action ofthe two dies g cndp, and the part Vin advance' of the diefwill be bentdown into a U-form. This having been done,`the carriage M will be.immediately raised upward to its highest position, and the advance ofthe carriage G will follow. I n going forward,

so,so4 2 the carriage G will press against the front lower bending andcutting-die g, and move it out of the'way, and pass in, and at' the sametime will draw the wire forwards, and force against the die n the partof the wire previously bent in the U-form. The legs of this portion willbe compressed together, and thus the parta, shown in-g. 4, willrbeformed. Next, the carriage G will boretracted, the wire will remain atrest, and the die f will be moved beek to its rearmost position. Thecarriage will next descend, and sever the blank from the wire.

I claim the combination of friction-jaws d e, or the equivalent thereof,and the dies and cutters fg 'n o p, arranged and provided with.mechanism substantially as described, for 'operating them in manner andfor the purpose as speoied.
